[texts]2. Robotics IJRRD GRAPHICAL ANALYSIS OF Nita Shah
It is simple for humankind to steadily walk on different terrain, but it is hard to achieve a human-like gait for bipedal walking robots due to their complex dynamics. In general, there are two approaches towards controlling a bipedrobot: static and dynamic walking. In this paper, we demonstrate the dynamic walking approach for controlling a biped robot. In this approach, the walker moves only under the gravitational force...

[texts]3. Robotics IJRRD LOCAL STABILITY ANALYSIS Nita Shah
The bipedal walking is the main form of locomotion of human kind. The human body is flexible and so it is easy for humankind to steadily walk on the different terrain, howeverbuilding arobot to have a human-like gait is not easy due to the complex dynamics of the walking.In this paper, we focus the passive dynamic bipedal robot (PDBR) which walks only by thepresentof gravity on an inclined ramp, that is, the robotis walking on a ramp in absence of external forces...

[movies]MIT 6.832 Underactuated Robotics, Spring 2009 - MIT OpenCourseWare
Instructor: Russell Tedrake Robots today move far too conservatively, using control systems that attempt to maintain full control authority at all times. Humans and animals move much more aggressively by routinely executing motions which involve a loss of instantaneous control authority. Controlling nonlinear systems without complete control authority requires methods that can reason about and exploit the natural dynamics of our machines...
